Overview:
==============================================================================

Grid-independent offline biogenic VOC emissions are now available for GEOS-Chem
at native MERRA-2 (0.5° x 0.625°) and GEOS-FP (0.25° x 0.3125°) meteorology
field resolution. These emissions were generated with GEOS-Chem 12.3.0. The
files in this directory were generated using Yuan-processed MODIS LAI (in
Yuan_XLAI/v2019-03), as as opposed to files in OFFLINE_BIOVOC/2019-08 which
used the older MODIS LAI product (in MODIS_XLAI/v2017-07).
